1. INTRODUCTION

The C95 CI is a totalling digital panel meter. The totalling function allows converting any instant value, after integration, into a cumulated magnitude.

It can be connected to a flowmeter to display the instant flow and the cumulated volume or weight, and also to a converter, for instance a power converter to display the instant power and the energy consumption of an installation.

General features

-Instant value display on 5 digits (14mm) with scale factor adjusting from -99 999 to 99 999

-Cumulated value display on a 6 digit counter (14mm) associated with a second overstepping counter, allows totalling from -99 999 999 to [phone]

-Totalizer memory saved in case of power supply cut

-Programming of the integration time (sec, min, hours) and of

a convertion coefficient (from 0,0001 to 999999)

- A bargraph allows a quick evaluation either of the instant value or the cumulated value, and can also be used as indicator for various functions (overstepping, LOGIC input, RS, etc...)

• Input :

-Direct current or voltage, bidirectionnal ±100mV, ±1V, ±10V, ±300V, ±20mA

-Measurable scale overstepping from -5% to +5%

-Input impedance ≥1MΩ for voltage inputs

drop 0.9V max for the current input

-Enlarging effect possible

-Linear input with or without square root extraction and special curve on 20 pt (programmable in X and in Y).

-Supply for 2 or 3 wire sensor for the current input : 26 VDC (±15%) 100mA protected from short-circuits.

• Transfer :

-Accuracy 0.05% of full scale at 25°C

-Thermic drift <150 ppm / °C

-Sampling time : 100ms

-Filtering : Programmable integration time (10 coefficients)

-Common mode rejection rate : 130 dB

-Serial mode rejection rate : 70 dB 50/60 Hz

-Insulation : Input / Power supply : 2.5kV 50 Hz 1 min

Input / Output : 2.5kV eff. 50 Hz 1 min
